The Fischbach rises on the southeast flank of the central Idarwald , about 2.4 km west of Schauren am Steingerüttelkopf at an altitude of 632 m above sea level. NHN . In the upper reaches some smaller brooks that also flow off the south-eastern flank of the Idarwald. The 1.6 km long spring stream is worth mentioning here . The use of water power by mills begins below the estuary. In the further course the Fischbach flows mainly to the southeast.
First the stream reaches the Hammerbirkenfeld residential area , which is on the left bank. From Hammerbirkenfeld the stream is called Hammerbach . The Mombach flows a little below . On the following stretch of the river, several smaller streams flow from the Mörschieder Forest from the south. Among them the Kempfelder Bach and the Schwarzborner Graben . Then the stream reaches the Harfenmühle and to Asbach belonging Asbacherhütte . From here the river is called Asbach . The Ebesbach, coming from the north, flows below the Weidener Mühle . From this confluence, the river is now called Fischbach again.
A few kilometers further downriver, the river reaches Herrstein and then Niederwörresbach . The Wörresbach, coming from the northwest, flows here on the right . In the following stretch of water, the Wahlenbach , Tiefenbachsgraben and Seitzenbach coming from the southwest also flow on the right , before the Fischbach reaches the Fischbach town of the same name . The Hosenbach flows here on the left , which is 13.5 km in length and is the most important tributary of the Fischbach. From the southwest the Fischbach then flows to the Atelbach , before it rises to 212 m above sea level. NHN flows into the Nahe .
On its 21.3 km long path, the Fischbach overcomes a height difference of 420 m, which corresponds to an average bed gradient of 19.7 ‰. It drains a catchment area of 97.648 km².

The Fischbach is a coarse material rich, silicate low mountain range. Its water structure is classified as significantly changed over long stretches. However, longer sections in the middle and lower reaches have been greatly or completely changed. The water quality is consistently classified as slightly polluted.
